May 11, 2007

Appl. No.:

12/227321

Inventors:

Ailan Guo - Burlington MA, US
Jeffrey Mitchell - Nashua NH, US
Peter Hornbeck - Magnolia MA, US

International Classification:

G01N 33/566
C07K 16/18

US Classification:

436501, 5303879

Abstract:

The invention discloses 432 novel acetylation sites identified in signal transduction proteins and pathways underlying human protein acetylation signaling pathways, and provides acetylation-site specific antibodies and heavy-isotope labeled peptides (AQUA peptides) for the selective detection and quantification of these acetylated sites/proteins, as well as methods of using the reagents for such purpose. Among the acetylation sites identified are sites occurring in the following protein types: Acetyltransferases, Adaptor/Scaffold proteins, Actin binding proteins, Adhesion proteins, Apoptosis proteins, Calcium-binding proteins, Cell Cycle Regulation proteins, Cell Surface proteins, DNA binding proteins, DNA replication proteins, Channel proteins, Chaperone proteins, Cellular Metabolism enzymes, Cytoskeletal proteins, DNA repair proteins, Endoplasmic reticulum proteins, Enzyme proteins, G protein and GTPase Activating proteins, Guanine Nucleotide Exchange Factors, Helicase proteins, Isomerase proteins, Extracelluar matrix proteins, Hydrolases, Ligase proteins, Lipid kinases, Inhibtor proteins, Lipid Binding proteins and Lyases.

US Patent:

62263749, May 1, 2001

Filed:

Nov 24, 1998

Appl. No.:

9/198941

International Classification:

H04M 342

US Classification:

379207

Abstract:

Existing and new service provisioning capacity in an AIN is determined by calculating processor utilization. Existing service demand and component usage information is automatically acquired from the AIN. ISP service data and SCP configuration descriptions are updated as needed. For each new service modeled, a call processing record is developed. A time of day usage for each service is also entered. For each city in the region covered by the AIN, demand forecasts for each new service in the city is determined. Utilization is determined for SCPs, ISPs, and SPACE systems provisioning capacity.

International Classification:

G06F 1300
G06F 1314

US Classification:

364200

Abstract:

One of a plurality of devices on a common communications path (68) has a local memory (54) that is accessible by other devices on the common communications path (68). Another device on the common communications path (68) may include a cache memory (190) that keeps copies of certain of the data contained by the local memory (54). If another device on the common communications path (68) accesses the local memory (54), the cache (190) is kept apprised of this fact by monitoring of the common communications path (68), and it sets an internal flag to indicate that the data involved may not be valid. However, the contents of memory 54 may also be accessed by means of a processor (50) without using the common communications path (68). Accordingly, provisions are made to send an invalidate signal over the common communications path (68) when a non-path access of the local memory (54) has been made to a location to which access was previously afforded over the common communications path ( 68). In this way, non-path accesses of a local memory can be permitted, yet proper invalidation of cache memories can be performed in a simple manner.

Abstract:

The invention relates to a method of cell culture where the cells are modified to reduce the level of synthesis of growth and/or productivity inhibitors by the cell. The invention also relates to a method of cell culture for improving cell growth and productivity, in particular in fed-batch culture of mammalian cells at high cell density. The invention further relates to a method of producing cells with improved cell growth and/or productivity in cell culture and to cells obtained or obtainable by such methods.
